Brother HL-2140 toner light stays on after toner was replaced in cartridge

Wow Dennis. This is the only thing that worked. My Brother HL2140 was flashing all of the lights and when you held down the blue button, the toner light stayed on. We tried about 15 different solutions including the tape over the sensors. This worked, I felt like I was sending some secret code. Awesome. THANK YOU SO MUCH!!!! THIS WAS AN EXPENSIVE PRINTER
